to be sure, but I think I'm going to like it-haven't been using it long enough to know. They say to give cosmetics a minimum of 30 days before making a judgment. I do know that many eye creams I've tried have turned my undereye purplish immediately upon use. Can't imagine what it is unless it's an ingredient my chemistry doesn't like. This one isn't doing that and I feel a very slight firming which is what I'm after. I'll need a couple of more weeks to know for certain. I'm not looking for an eye cream that 'goes on smoothly' or 'feels so good.' Any cream will do that. I'm hoping for much more out of these peptides.
